Deep water warming in lakes: an indicator of climatic change

Abstract

The deep waters of Lake Maggiore, Italy (Zmax =370 m) contain a sort of "climatic memory", represented by variations in the caloric content, which has been located in time and space, and its energitic value calculated on the basis of the depth of the winter misxing, the heat exchange in deep waters and the K2-N2 correlation's during the summer stratification.........

Keywords

• deep lakes, vertical mixing, long-term trend of heat content, climatic memory
